to be honest its really for you to decide. On one hand the G34 will have a better upgrade path in the long run. However, the 1207 processors are getting cheaper and cheaper for higher clocks, and still have hex-core upgrade options. You can grab what you can afford now, but upgrade cheaply from a 16-core @ 2.2Ghz to a 24-core with the same or higher clocks down the road. Its really up to you.
